it just comes down to willingness to stop and chat with each other. at a company of sufficient size everyone is in different offices/cities/countries anyways so you'll always hit some sort of odd issue. You just have to be able to control what you can.

For me, being in office would add nothing, because my team is split between two cities, and if i ask a question outside of my team its highly likely we're talking about crossing oceans.

Like anything, its about communication
